United States Patent M 3,059,629 BOW STRING SILENCER Robert E. Stinson, Box 135, Mayfield, Mich. Filed Nov. 1, 1960, Ser. No. 66,485 3 Claims. (Cl. 124-23) The present invention relates to archery, and in particular to a means for deadening or silencing the vibration nodes at points where they develop in the bow string.

An important object of the present invention is to provide a silencer for a bow string wherein bow string noise will be dampened by deadening vibration nodes at the points where they develop in the string so that for example deer will not flinch or duck at the sound of the string twang, and wherein the elimination of the string twang or how string noise will insure that the hunter will not have his location given away when an arrow is shot.

A further object is to provide a bow string silencing attachment which will dampen out how string twang by deadening vibration nodes at points where they peak in the string when the bow is shot, so that animals or game will not be able to locate the position of the hunter from the sound of the string, and wherein the elimination of the sound will insure that the animals or game will not be able to hear the sound and flinch or duck or otherwise be forewarned of the shooting of the arrow.

A still further object of the invention is to provide a bow string silencing means that includes a pair of body members that are mounted in spaced apart relation on the bow string, and wherein there will be no interference with use of the bow in shooting an arrow and wherein the present invention can be readily attached to the bow string when desired or required.

A still further object of the present invention is to provide a bow string silencer which is fool proof in use and rugged in structure and which can be made in such a manner that uniform efliciency will be assured and wherein production thereof in quantities can be accomplished at reasonable cost.

As will be more fully described and particularly pointed out in the appended claims, the invention consists of certain novel features of construction and certain additional objects of the present invention will become apparent with reference to the following description of an embodiment of the invention and in which description reference will be had to the accompanying drawings illustrating the said embodiments and referring to the drawings:

FIGURE 1 is an elevation view showing a bow with the silencers of the present invention mounted on the bow string.

FIGURE 2 is an enlarged elevational view of one of the silencers or how string attachments per se.

FIGURE 3 is a view taken at right angles to the View shown in FIGURE 2.

FIGURE 4 is a sectional view taken on the line 4-4 of FIGURE 2.

FIGURE 5 is a perspective view showing the mounting of the bow string silencer on the bow string.

Referring in detail to the drawings, the numeral indicates a conventional bow which includes end portions 11 and has the usual bow string 12 affixed thereto in any suitable manner, and according to the present invention a silencing means is provided for the bow string 12 and this silencing means comprises a pair of attachments or silencers which are indicated generally by the numeral 13. Each of the silencers 13 has the same construction and each is made of a suitable yieldable or resilient material such as a rubber like or plastic like material and it is of one piece construction and is shaped to include a body member that is indicated by the numeral 22. Each of the body members 22 includes a central hub portion 14 which is provided with tapered or inclined outer surfaces 15, and each hub 14 includes a central aperture or opening 17 for the projection therethrough of the bow string 12. Each body member or silencer further includes three equally spaced apart arms 16 which are provided with longitudinally extending ribs or shoulders 18 on their outer surfaces, FIGURE 2. The arms 16 are perfectly arranged radially with respect to the hub 14, and these arms 16 may be spaced apart one hundred and twenty degrees with respect to each other.

In FIGURE 1 the numerals 19 and 20 indicate in dotted lines the vibration nodes which occur in the bow string 12 when the bow is shot, and the silencers 13 are mounted at the peak points as indicated by the numeral 21.

It will be seen that according to the present invention there has been provided a bow string silencer which is adapted to be used for preventing twang or noise when the bow is used and as shown in FIGURE 1 for example a pair of the silencers 13 are adapted to be mounted on the bow string 12 at the peak points 21. The silencers 13 each have the same construction and each includes a body member 22 of one piece formation which includes the central hub 14 that has an opening 17 therein for the projection therethrough of the bow string 12 and the opening 17 is of such a size that the string 12 will snugly project through the opening 17 whereby accidental displacement of the silencers from their desired or proper position on the bow string 12 will be prevented so that the section between the hub 14 and the bow string .12 will help prevent sliding movement of the silencer on the bow string. Each of the silencers includes the arms 16 which have the longitudinally extending ribs 18 on the outer surfaces thereof and these ribs or shoulders 18 provide stiifening means so as to help maintain the arms 16 in their proper extended location whereby the arms will not readily move from their proper positions.

The present invention will dampen out bow string twang by deadening vibration nodes at the points where they peak as indicated by the numeral 21 as shown in FIGURE 1 when the bow is shot, and the dotted lines indicated by the numerals 19 and 20* show the vibration nodes which occur when the arrow is shot from the bow. The purpose of the silencers 13 which are located at the peak points 21 is to prevent deer or other game or animals from flinching or ducking the arrow due to the loud twang of the bow string 12, and in addition the silencers 13 will prevent game from locating the position of the hunter from the sound of the string.

Due to the space between the arms 16, the silencer will have a minimum amount of weight so that there will be no interference with normal use or movement of the bow string, and the ribs 18 as well as the enlarged shoulder 14 help provide suificient rigidity or stability for the silencer so that the device will function in the desired manner. The bow string attachment of the present invention will dampen the bow string noise by dampening vibration nodes at the points where they develop in the string, and the silencer of the present invention can be used for various types of bows. Thus, the silencer of the present invention silences the loud twang made by the tension of the string itself when the arrow is shot.

Minor changes in shape, size and rearrangement of details coming within the field of invention claimed may be restored to in actual practice, if desired.

Patented Oct. 23, 1962 What is claimed is:

1. In a device of the character described, a bow having a string attached thereto, a pair of silencers frictionally mounted on said string and said silencers being arranged in spaced apart relation with respect to each other, each of said silencers comprising a body member made of yieldable material and having a one piece formation, each body member being provided with a central hub having an aperture therein for the projection therethrough of the string, the outer surfaces of the hub being tapered, a plurality of equally spaced radially disposed arms arranged approximately one hundred and wenty degrees apart on said hub, and ribs on the outer surfaces of said arms extending parallel to the longitudinal axes of the arms, said silencers serving to dampen out how string twang by deadening vibration nodes at points where they peak in the string when the bow is shot so that game will be prevented from fiinching or ducking the arrow due to the loud twang of the bow string, and wherein game will be prevented from 2 locating the hunter from the sound of the string.
